| 摘 要： | 对超厚度强湿陷性黄土地基应用(灰)土挤密桩桩周土体密实度变化规律进行试验研究。试验证明,(灰)土挤密桩能有效改变其密实度,从而降低其湿陷性;单桩的有效挤密半径为单桩直径的1.5倍左右,群桩可以认为是各单桩挤密效应的简单叠加;用(灰)土挤密桩处理地基完全可以达到以土治土、节约成本的目的。

| Abstract: | Dense degree of soil around lime soil compaction piles in huge thickness and serious collapsibility loess ground is investigated with experiments. The results show that lime soil compaction pile can change soil compactness and reduce its collapsibility efficiently, the diameter of compactness effect of a pile on loess can reach 1.5 times of the diameter of the pile, and the compactness effect of pile group is the sum of the single pile. The method of treating loess with lime soil compaction pile is economical. |
